WIRE-STRETCH ER.

srnorrronrron formingpart of Letters Patent No. 629,240, dated Jul 18, 1899.

Application filed N ovemhel 3, 1888- Serial No. 695,399. (No model.) I

To all whom it may concern: 7

Be it known that I, J OHN W. DARLINGTON, a citizen of the United States, residing at Denison, in the county of Jackson and State of Kansas, have invented certain new and useful Improvements in Wire-Stretchers; and Ido de-. clare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it ap-. pertains to make and use the same, reference beinghad to the accompanyingdrawin gs, and to the figures of reference marked thereon, which forma part of this specification. v

My invenion relates to wire-stretchers; and its object is to provide an improved construction of the same by means of which fencewires may be stretched or tightened in a rapid and efficient manner.

The invention consists in the novel construction'and combination of parts herein after fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a fence-wire stretcher constructed in accordance with my invention. Fig. 2 is a plan view of the'same.

V In the said drawings the reference-numeral 1 design ates a bar formed in the opposite edges with notches 2 and at one end is provided with a fixed clamping-jaw 3. Pivoted to this end of the said bar is a serrated cam-lever 4:, between'which and the said jaw the wire to be stretched is clamped.

, The numeral 5 designates a metal plate provided with a hooked arm 6, which when in use is adapted to rest against a fence-post.

a [Formed integral with said plate are two lugs 7, formed with rectangular holes through which said bar passes. 7 g

p The numeral 8 designates a levercomprising the handle and two parallel'armsi) secured thereto and embracing said bar. Pivoted to,

said plates above and below'the bar are two curved dogs'lO, one end of which is adapted to engage with the notches in the bar, while the other end is curved, as seen at 12, and

adapted to engage with the beveled portion 18 of one of the lugs 7. V

The operation is as follows: The hooked arm 6 is placed against a fence-post and the wire to be stretched is clamped between the jaw 3 and cam -1ever 4: and securely held against slipping. The lever 8is then operated, being moved back and'forth, the dogs alternately engaging with the notches in the bar, so that at each forward movement of the dogs the bar wili be moved forward, thus stretching the wire. Upon the backward movement of the dogs their rear curved ends 12 will strike the beveled portion 13 of the rear lug 7 and riding thereon will insure the dog being turned on its pivot, so that the other end will engage with one of the notches. v a

The device may also be used as a lever by turning it around thepost, thus tightening the wire.

Having thus fully described my invention,

what I claim is.--

In a wire-stretcher, the combination with a plate formed with a rigid hooked arm, and with apertured lugs, one of said lugs being beveled at opposite sides, of a notched bar extending through the lugs, and provided at one end with an integral jaw, a eam lever pivoted to the end of the notched bar and cooperating with said jawya lever provided with parallel plates'embracing the bar, and the oppositely-arranged pivoted dogs, having their rear ends rounded to cooperate with the beveled surfaces of the lug.

In testimony whereof I aiiix my signature in presence of two witnesses. V
